Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Noaa Cdo MCP Server — questions

Answers built from our own checks of this server.

Is Noaa Cdo MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 11 ms. The bar chart above shows every period we have measured.
The registry lists Noaa Cdo MCP Server as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Noaa Cdo MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Noaa Cdo MCP Server need an API key?
No. Noaa Cdo MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
How many people use Noaa Cdo MCP Server?
The npm package @cyanheads/noaa-cdo-mcp-server was installed 68 times in the last week. Week over week that is +480%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Noaa Cdo MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 4 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
